VENTILATOR.

Specification of Letters Patent. Patented Sept. 8, 1914.

Application filed March 26, 1913. Serial No. 7561857.

invention relates to ventilators adapted to be set in an opening provided in the inclosure of a dwelling place for the purpose of permitting passage of air. The general object of ventilators so used is to control this passage so as to avoid strong and direct drafts, to limit it to air only and to exclude rain, insects and matter floating and carried by the air.

My invention consists of a ventilator of this type constructed in a certain manner which is so as to permit it to be readily placed in position within an opening, which may be a window-opening, and which ex eludes rain and insects'without interfering with its principal function of permitting passage of air.

In the following specification and particularly pointed out in the claim at the end thereof, will be found a full description of the invention, together with its parts and construction, which. latter is also illustrated in the accompanying drawing, in which Figure 1, shows the ventilator in frontview and before being placed in position. Fig. 2, shows it in a similar view, after having been attached in position within an opening which may be a window-opening. Fig. 3, shows it in a top view as it appears when a horizontal section is taken through the frame of the windowopcning shown in the preceding figure. Fig. 4, is part of an enlarged front view and illustrates manner of construction. Fig. 5, shows an enlarged vertical cross-section of the ventilator taken between its ends.

My invention is more particularly intended for use in connection with window-openings and it is constructed according so as to permit ready connection within such an opening and without interference with the use and operation of the window.

In the drawing, A is the ventilator proper, it consisting of a flat piece of sheet-metal which is multi-perforated as shown at a and of a size to suit the opening where it is to be used. In this case the ventilator is intended to be used in connection with a window,- openmg and within a space resulting when a sash has been partly moved from its closed POSltlOIl the ventilator remaining stationary and1 not sharing in the movements of the sas The ventilator is attached in position as best shown in the drawing and connected to the window-frame by any suitable means such as nails or screws which are applied at the ends of the ventilator as shown at 77.

In order to preventrain or snow from cntcring through openings a and to retard passage of matter carried by the air, I provide on the outer side of the ventilator a shedding member B which has parallel ridges consisting each of the horizontal part 8 and the shedding part 9 which inclines from the horizontal part inwardly toward the ventilator. Openings 6 are provided in these horizontal parts which coact with openings or to permit passage of air. Water is excluded by reason of the location of these openings and. by means of the inclined partabore them which drains the water outwardly. The relative arrangement of openings a and b in different planes, in a vertical plane as to the first and in a horizontal plane as to the others, also favors the exclusion of matter floating in the air and counteracts formation of direct drafts. This action is further aided by avoiding alinement of the openings and by arranging them instead as shown, that is by having those in one member opposite the solid spaces between those of the other member.

The two members A and B may be connected to each other in any suitable way or by using parts of the metal of one member to engage the other member. For such purpose, the metal of member A is cut in oer tain places as shown and the separated parts are turned up to form lugs 10 which are turned over one edge of member B. The other edge of this member is engaged by the juxtaposed overturned edge 11 of member A. The tortuous passage due to the relative po-. sitions of openings (1 and I), does not favor the entrance of insects, but the possibility may be guarded against by interposing wire cloth 12, between members A and B. This may be secured to one member before the other member is placed in position, solder' being a preferable means for its connection.

I Member B extends across the full width of the ventilated opening but inasmuch as window-frames do not always measure up uniformly to a given size, provision is made for endwise fitting. This is accomplished by having part of this member in orm of a movable section. This feature may be readily understood by comparing Figs. 1 and 2, the latter figure showing the device fitted fully into the opening. The sections meet with suflicient lap, so that no unpro tected gap results by reason of this adjustment.

Having described my invention, I claim as new:

In a ventilator, a ventilating member consistin of two endwise alined sections, a fiat plece of sheet metal having ventilating perforations adapted to be attached to a window" frame and serving as a supporting member for the sections mentioned, said su iporting member bein provided with with reference to the other section, these latter being shaped to form horizontal portions which are perforated to permit passage of air and inclined portions between these horizontal portions to shed rain.

In testimony whereof, I hereunto afiix my signature in the presence of two witnesses. JOHN C. SCOTT. Witnesses:
